ROLLER SKATE.

Application filed March 11, 1925. Serial No. 14,638.

This invention relates to improvements in skates and more particularlyto roller skates of the two or three roller type; it being the principalobject of the invention to provide skates of the above character whereinthe rollers are supported through the intermediacy ofshock absorbingsprings.

Another object is to provide skates having the rollers arranged in thecentral longitudinal line of the skate as distinguished from beingarranged in pairs as is ordinary practice. V

A still further object resides in the provision of means whereby theskate may be adjusted to difi'erent lengths and secured at the differentpositions of adjustment.

Another object resides in the provision of. a three-roller skate whereinthe central roller is mounted slightly below the line of the two endrollers in order that only two rollers of the skate will be in contactwith the floor at a time.

Other objects reside in the details of construction and combinationofparts whereby the toe and heelsections are joined rigidly substantiallyand adjustably together.

In accomplishing these and other objects of the invention, I haveprovided the improved details of construction, the preferred forms ofwhich are illustrated in the accompanying drawings, wherein Figure l isa side view of a three-roller skate embodying the present invention.

Figure 2 is an under side plan view of the same. i

Figure 3 is a transverse section taken through a roller and itssupporting bearings.

Figure 4 is an enlarged, transverse section taken on the line 4-4 inFigure 1.

Figure 5 is an enlarged, transverse sectional view showing the clampingmeans whereby the skate may be secured to the sole of a shoe. c

Figure 6 isa side view of a two-roller skate.

Referring more in detail to the several views of the drawings- 1 and 2,respectively, designate the heel and toe plates of the skate which arejoined adjustably and held rigidly in functional relation by means oftwo overlapping ribs 3 and 4; the former of which is secured centrallybeneath and longitudinally of the heel plate and is adapted to slideupon the rib 4 which is secured likewise to extend rearwardly from thetoe plate. Each of these ribs 3 and 4, as is shown best in Figure 3, hasa fiat central portion from which flanges are turned downwardly alongopposite sides. Rivets 5 and 6 are extended respectively through theseflanges and through parts that support the roller, presently described,to hold the ribs rigid. The former portion of rib 8 is adapted to movetelescopically between the upper side of rib 4. and under face of thetoe plate 2, and its flanges slide upon the flangesof the rib 1 andwithin the upturned edge portions 4 of the latter, as is shown best inFigure 4. Thecentral portions of the ribs 3 and t are provided withlongitudinallydirected and registering slots 7 or provided with a seriesof registerable apertures and the heel plate with an opening 8 throughwhich a set screw 9 is extended and which has a nut 9 adapted to betightened to lock the parts at the different positions of adjustmentthat may be made.

Secured to the under sides of the heel and toe plates are rollermountings; those of the heel plate being for a single roller andcoinprises two metal housings 10' and 10 secured by rivets 11 throughoutturned flanges 12 along their upper edges. These housings aredisposed in spaced relation and a roller 13 is mounted between them on atransverse shaft 14, the ends of which extend through slots 15 in thehousings and are mounted in blocks 16 that are adapted to move slid--ably in upwardly and forwardly directed guideways 17 formed by thehousings. Coiled springs 18 are contained in the housing guideways, andthese bear against the upper ends of the blocks 16 to yieldably resisttheir upward movement and thereby absorb all shock and jar on theroller. The roller is rotatably mounted on the cross shaft through theintermediacy of a double set of ball bearings, as shown at 9-0, and isspaced to prevent rubbing contact with the housings by means of washers21 at its opposite sides.

Secured to the under face of the toe plate are housings 22 and 22" formounting two rollers 24 and 25 in a line centrally of the plate and inline with the heel plate roller. The central roller 24 is disposedsomewhat below the line of the two end rollers in order that only tworollers will contact with the floor at the same time. These rollers are'fixed to blocks operating in gruideways 31 and the guideways 29 and 31,at opposite sides at: the rollers. are. inclined upwardly and towardeach other as shown in Figure 1.

Secured to the rear edge of the heel plate 1 is a retainingflange :t'orholdingthe skate properly on the heel of the user and secured to the toeplate are clalnps 36 and 37 for engaging opposite edges out the sole ofthe shoe of the user. These clainps are connect ed by and may beadjusted by the rotation of a right and left hand screw 38 as isprovided on skates now in use.

In Figure 6. as shown a two roller skate diilers from the one justdescribed in that the toe plate has only one roller attached thereto.this skate being; more suitable for childrens use. 7

\Vith a skate of the above character, it is possible to adjust it tosuitable length by loosening the nut 9 and adjusting the ribs and l uponeach other. The adjustment may be retained then by tightening the nut.

It is also apparent that by the use of the spring mountings for therollers, all shock or jar is absorbed and an easy, cushioning effect isprovided.

Having thus described my invention, what I claim as new therein anddesire to secure by Letters Patent, is:

1. In a skate ot' the class described, a heel plate, a toe plate,rollers mounted on said plates. a rib fixed to the heel plate andextended forwardly thereof having a slot therein and having downturnedflanges along its side edges, a rib fixed rigidly to the toe plate toextend rearwardly therefrom and adapted to be OVGl'ltIPPGCl by the firstnamed rib and having a slot therein and having downturned flanges alongits side edges with upturned edges 'lorn'iing channels whereir theflanges of the first named rib are adapted to fit and a locking boltextended through said rib slots to lock the same together at differentpositions of a dj ustinent.

2. In a skate. ot' the'elass described comprising relatively adjustableheel and toe plates, a series of supporting rollers inounted inalineinent centrally beneath said plates comprisinga forward roller, arearward roller and a central roller; the latter being; mounted slightlybelow the line of the two end rollers. all of said rollers beingprovided with yieldable n'iounting hearings which permit the rollers toaline with each other when sufi'ieient weight is placed on the skate.
